adjusting size of flip animation outside of container

[beanmatt]

Is there a way to adjust the size of the animation so that it goes more/less outside of the container than the default animation?

you can just change this css properties

    -webkit-perspective: 1300px;
    perspective: 1300px;

they set on .bb-bookblock in bookblock.css
the larger the number the less it goes out
